Two-way Speech-to-Speech Translation

BBN Technologies’ TransTalk™ is a portable, two-way translation device that facilitates the exchange of information across language barriers.

English language speech is automatically translated and spoken in the foreign language. The foreign language speaker’s response is then automatically translated into English. BBN’s speech-to-speech translation technology is language independent and can be configured for any language pairing.
